Scott Deboy commented on LOG4J2-155:
------------------------------------
A few things to notice:
I need the ability to determine if a username and password is
required..hopefully the Commons VFS API provides this and I won't need to
modify the createAppender methods.
SocketAppender has a similar additional single parameter for
advertiseViaMulticastDNS..although in the 21 Feb patch this parameter was added
in front of the Layout parameter...I'll have to sync those up..
Also, the port and address multicast DNS 'properties' added by
AbstractSocketManager may be redundant...they aren't currently being used..I
will have to think if there is a useful use case for using them (multiple
interfaces on a box maybe, and the admin wants to be able to specify which
interface is used for tailing the log files?)

> I was looking at an old rev - getContentType is now exposed - thanks!
> Now if we could add a 'getFormat':
> It would be useful to expose information about a Layout's format.
> If the content type is text/plain, exposing the layout format as a conversion
> pattern would work fine.
> If the content type is text/html or text/xml we could expose something else
> (or null).
> My primary interest is adding the ability to 'discover' the file-based
> logging configurations in order to support them via Chainsaw and multicast
> DNS.
> If all Layouts supporting text/plain content types exposed their format as a
> conversion pattern, and the file-based appenders (optionally) provided the
> ability to advertise their configuration, the files could be remotely tailed
> without the far endpoint even knowing anything about the file configuration.
> For an example, see how multicast appenders are exposed via
> zeroconf/multicast dns in log4j 1.x in activateOptions - something very
> similar could be done with contenttype and format properties in a
> fileappender with a layout.
> if (advertiseViaMulticastDNS) {
> Map properties = new HashMap();
> properties.put("multicastAddress", remoteHost);
> zeroConf = new ZeroConfSupport(ZONE, port, getName(), properties);
> zeroConf.advertise();
> }
